Ngokunyuka kwamandla etrektara yasekhaya, iimfuno zeshafti yothumelo ziya zinyuka nangaphezulu, ngoko ke siye saphuhlisa amandla amakhulu ehashe, itorque enkulu, iAngle yothumelo enkulu. Nangona imodeli efanayo yecandelo lomnqamlezo isetyenziswa, siqala sandise ityhubhu yangaphandle kunye ne-shaft, siphucula i-torque kunye nokwandisa amandla. Okwesibini kukusebenzisa izixhobo eziqhelekileyo, ezincinci kwizikhonkwane, ezinkulu kumbhobho wangaphandle kunye ne-shaft. Sikhetha iteknoloji eyenziwe ngokwezifiso kunye nezixhobo eziphezulu, ezichanekileyo kwaye zingcono kuneemveliso eziqhelekileyo. Ithengiswa kakhulu eTshayina.
